The Component Repository

When you invoke the eCos Configuration Tool, it accesses the Component Repository, a read-only location of configuration information. For an explanation of “Component Repository” see Chapter 24.

The eCos Configuration Tool will look for a component repository using (in descending order of preference):

• A location specified on the command line

• The component repository most recently used by the current user

• An eCos distribution under /opt/ecos (under Linux) or a default location set by the installation procedure (under Windows)

• User input

The final case above will normally only occur if the previous repository has been moved or (under Windows) installation information stored in the Windows registry has been modified; it will result in a dialog box being displayed that allows you to specify the repository location:

Note that in order to use the eCos Configuration Tool you are obliged to provide a valid repository location.

In the rare event that you subsequently wish to change the component location, select Build->Repository and the above dialog box will then be displayed.

You can check the location of the current repository, the current save file path, and the current hardware template and default package, by selecting Help->Repository Information.... A summary will be displayed.
